Description Christian Lepine 2001-02-07 00:56:18 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [fr] (X11; U; Linux 2.2.16-22 i686)


The man page of ftphosts says that when I use deny username addrglob, hosts
maching addrglob logging in as username will be deny.
Actually, the username is always deny even if he is from another addrglob.
I have try :
deny tux 192.168.1.100

and

deny tux *.maison

And I always get a deny even if the user tux is comming from another
address or domain ???? 


Reproducible: Always
Steps to Reproduce:
1. enter a deny directive for a user maching an address in /etc/ftphosts
(deny tux 192.168.1.100)
2. Try to connect from another address but with that username (ncftp -u tux
ftp.maison) note that the client address is not 192.168.100.
	

Actual Results:  It won't connect

Expected Results:  The user tux is not comming from address 192.168.1.100
so he should be able to connect

verified even with IPs of xx.xx.xx.xx/mask. Regardless of the IP, the access
for this user will be denied. (wu-ftpd-2.6.1-12)
Comment 2 Bernhard Rosenkraenzer 2001-02-07 14:37:13 UTC 
Yes, wu-ftpd's algorithm for determining these things is ultimately broken
and needs a rewrite. pHtmp is ALWAYS NULL if a matching entry is found
but does not apply.
I'll fix this later today.
